nexus of money on Instagram: "Most vehicles accelerate. This one teleports. 🤯🚀 You are watching a test of China's "T-Flight" hyperloop, a system that has just set a world record by accelerating a one-ton vehicle to over 700 km/h (435 mph) in just two seconds. This isn't a train; it is a demonstration of pure electromagnetic physics. The pod levitates using powerful magnets to eliminate friction, while a linear synchronous motor—essentially an "unrolled" electric motor stretching the length of

Fred Duncan on Instagram: "You don’t need to toe drag. Most young athletes try to toe drag because they’ve seen it in some elite sprinters and assume it’s the cause of speed. That’s the first mistake. Actively dragging the toe doesn’t help you accelerate. Creating friction against the ground outside of true stance doesn’t move you forward faster. The second explanation people give is that a lower heel helps you get the foot back on the ground sooner so you can push. That idea only holds if it em
